  • Patent Literature 1 JP-A-10-122879 (pp. 2 to 3, FIG. 3)
  • Patent Literature 2 JP-A-2003-302238 (pp. 3 to 4, FIG. 1 and FIG. 9)
  • a navigation apparatus of the present invention for causing a display to display a facility image regarding a facility ahead of user's present location, includes a control portion controls whether or not a facility image is displayed on a display, based on operation data output from an operation switch when location data contains plural corresponding destinations on map data.
  • the term “facility” is a place that has an access road branched from the road.
  • the term “facility image” is an image that is used to guide the facility. As an example, there are a map of a parking lot, and the like.
  • location data is a concept that contains GPS data and various data calculated from GPS data and other data.
  • other data there are speed data, azimuth data, and the like.
  • map data is data in which the roads or the facilities are correlated with their location data.
  • location data contains plural corresponding destinations on map data means that two roads or facilities or more corresponding to the location data are present at least in the internal process. That is, there is uncertainty in the so-called map matching. This uncertainty is liable to arise in a branch point in the road, plural roads running in parallel mutually, a parking lot contiguous to the road, and the like.
  • the “control portion” causes the display to display a switch image used to decide whether or not the facility image is displayed when the location data contains plural corresponding destinations on the map data.
  • the “switch image” is displayed to cause the user to decide whether or not the facility image should be displayed, and consists of a character(s), a figure(s), a color (s), and their combination.
  • control portion causes the display to display the facility image and delete the switch image from the display when a number of corresponding destinations is changed from plural to single.
  • wording “a number of corresponding destinations is changed from plural to single” means that the road or the facility corresponding to the location data is defined solely at least in the internal process.
  • the “control portion” causes the display to display the facility image and delete the switch image from the display when facility specifying data transmitted from a facility side is present in a storage medium.
  • the wording “facility specifying data transmitted from a facility side” indicates the data transmitted from the equipment provided on the facility side. It does not matter whether such data should be transmitted via radio or transmitted via light.
  • a facility side is a concept that contains the facility itself and the access road connected to the facility.
  • the present invention possesses such an advantage that, when the location data contains a plurality of corresponding destinations on the map data, it can be controlled based on the operation data output from the operation switch whether or not the facility image should be displayed on the display and thus the facility image can be displayed usefully to the user.
